SLIDING-DOOR HANGER AND TRACK.

Specification of Letters I'atent.

Patented Feb. 25,1913.

Original application filed October 7. 1512, Serial No. 724,349. Divided and this application filed November 18, 1912. Serial No. 732,058.

To all whom it may concern.

Be it known that I, ORRIN WEIDRICI-I, a subject of the King of Great Britain, and a citizen of the Dominion of Canada, residing at 202 V entworth street-north, in the city of Hamilton, in the county of Wentworth and Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Sliding-Door Hangers and Tracks, of which the following is a specification.

This invention relates to sliding-door hangers and tracks, and more particularly to that type of device used in connection with the suspended doors of barns, grain warehouses, railroad freightcars and the like.

This invention is a divisional from my copending application, Serial No. 724,349, filed October 7th, 1912.

The main. object of my invention is to provide an improved combined door hanger and track adapted to be constructed from a single piece of sheet metal at a very small cost, and one which will provide the necessary trackway for the wheels of the hanger in one piece with the housing structure.

With these and other objects in view as will be apparent from the following description, my invention consists in the novel construction, arrangen'ient and combinations of parts hereinafter fully described, and particularly pointed out by the appended claims.

The accompanying drawing, forming a part of this specification, is an illustration of the invention, and exemplifies by a sectional elevation the adaptation of my improvements to a sliding door hanger and track suitable for grain warehouses and the like.

According to my invention, 1 construct the track from thin sheet metal, preferably galvanized iron, and form it with a vertical flange 1, for fixture against the wall or other structure to which the device is applied as by bolts 2, 2, for example. Obliquely inclined relative to said flange 1', l outwardly bend the sheet of metal to constitute a roofing3, and then downwardly bend said sheet to form a substantially vertical front facing 4. The. material is bent inwardly at the lower edge of the front facing 4 to form a basal, flange 5, which terminates in a longitudil'mlly extending tubular portion 7, Said grooved about its peripheral surface to snugly fit the aforesaid running surface 6, and said wheels may be either made entirely of compressed fiber, cast metal, or fiber sheathed with a steel rim or tire. The wheel 8, is loosely mounted upon a stub-axle 9, provided with a head 10, adapted to fit snugly against the said wheel 8, on its front face; and,-to'insure easy running, I use anti- .friction rollersll, around-said stub-axle 9.

12, is a spring washer, and 13, is a threaded extension of the stub axle 9, which is screwed into the hanger head 14, and afterward riveted over at 15, aswill be clearly understood on an examination of the drawing; a cross-cut-not shown-being provided in the head 10, for the screwing operation, while the riveting over at 15, insures absolute rigidity.

16, is the upper portion of the hanger, and it is preferably formed as shown; that is to say, the lower part thereof is fashioned wit-h hinge cars 17, to which the lower hanger portion 18, is hingedly connected by a through bolt 0r pin 19.

20, is a laterally projecting trough formed integral with the lower part of the upper hanger portion 16, and it has spaced relation to the tubular track 7, aforesaid.

Obviously, two or more hangers will be employed in connection with each door 21, which is suspended by bolts 22, from the lower hanger portion- 18, and I wish it clearly understood that I have only illustrated one hanger as the general arrangement of the entire device will be well known to those skilled in the art to which my invention appertains.

When the track is supported in position with. the wheels 8, in place, I close in the ends of the said track by cap piecesnot sho\vn-to prevent small birds and vermin from entering and fouling same.

From the foregoing description and accompanying drawings it will be readily seen that the suspended door 21, may be swung forwardly or upwardly, as well as longituthe ingress of dirt or rain and the like which interfere with the easy working of the device as well as tend to deteriorate the metal. Obviously changes in the shape, proportipns, and 'minor details may be effected without in any way departing from the spirit and scope of the invention, and it is intended to include all such within this application and as limited by the appended claims.

Having thus fully described my invention, What/I claim as new and desire to secure by Letters Patent, is

1. The combination in a device of the type described of a track formed with a suspension flange, a roofing integral therewith and projecting obliquely from the lower edge thereof and downwardly bent to constitute a front facing lying in a plane substantially vertical and parallel to said suspension flange, said front facing being inward] y turned at its lower parts into a horizont-al plane and longitudinally grooved to constitute a tubular running Way, wheels adapted tofit and traverse said tubular running way loosely mounted on stub-axles secured to the heads of upper hanger portions, said upper hanger portions being furnished with laterally projecting upwardly curved flanges adapted to prevent the track from being outwardly strained, and means for suspending said track in position and fixing said hangers to the door, substantially as set forth. i

2. A track and housing comprising in combination, the suspension flange, an' inclined roof extended therefrom, a front facing extending from said roof and a tubular running-way supported from said front facing substantially as shown and specified.

Signed at Hamilton, county of Went-- worth, Province of Ontario, Dominion of Canada, this 12th day of November, A. D.
